SWINGLETREE-HOOK.

Specification of Letters Patent.

Patented March 19, 1907.

Application filed February 8, 1906. Serial No. 300,161.

T0 all whom, it may concern:

Be it known that I, BENJAMIN F. EMERY, a citizen of the United States of America, and a resident of Thayer, Union county, Iowa, have invented a new and useful Swingletree- Hook, of which the following is a specification.

The object of this invention is to provide an improved construction for swingletreehooks whereby the function thereof in respect of retaining engagement with a trace or eockeye is materially improved.

A further object of my invention is to provide a combined swingletree hook and guard formed integral with each other.

A further object of my invention is to provide a combined swingletree hook and guard complete in one piece.

A further obj ect of this invention is to provide means for rigidly connecting a combined swingletree hook and guard to a swinvletree.

A further object of this invention is to provide means for pivotally mounting a combined swingletree hook and guard on a swin letree.

A further object of this invention is to provide means for mounting a swingletree hook and guard separately formed on a swingletree in contiguous and coacting relations.

My invention consists in the construction, arrangement7 and .combination of elements hereinafter set forth, pointed out in my claims, and illustrated by the accompanying drawing, in which- Figures 1 and 2 are top and front views, respectively, of one form of my device. Fig. 3 is a front view of a modified form of my device. Figs. 4, 5, and 6 are top, front, and ends views of a further modified form of my device. Figs. 7 and 8 are top and end views of a further modified form of my device. Figs. 9 and 10 are top and end views of a further modified form of my device, in which the combined swin'gletree hook and guard is mounted pivotally on a swingletree. Fig. 1 1 is an end view of a further modified form of my device, in which the combined swingletree hook and guard is mounted rigidly on a swingletree. Figs. 12 and 13 are top and end views, respectively, of a further modified form `of my device, in which the swingletree hook yand guard are sep arately formed and conjunctively mounted removably and replaceably on a swingletree.

In the construction of the device as shown in Figs. 1 and 2 the numeral 10 designatesl a socket removably and replaceably yet rigidly mounted on a swingletree 1 1. A stud or pin 12, in this instance relatively broad and flat, is formed on and projects longitudinally from the outer end portion of the socket 10 and is adapted to be embraced by the eye of a trace or cockeye and transmit strain o f a trace or tug to said swingletree. A guard is provided and is formed and shaped as follows: An arm 13 is formed on and rises from the socket 10 adjacent the inner end of the pin 12, a top bar 14 extends from an integral connection with the upper end of the arm 13 outwardly parallel with and above the pin 12, a rear extension 15 projects rearwardly from the outer end of the top bar 14, a vertical member 16 drops from an integral connection with the rear end of the extension 15, and a cross-arm 17 extends from an integral connection with the lower end of thevertical member 16 inwardly parallel with and below and to the rear of the pin 12 and terminates in an eye or boss l18. The cross-arm 17 may be omitted, if desired, and the eye or boss 18 be formed on the lower end portion of the vertical member 16. A trace or cockeye may be attached to this device by flexing the trace or tug outwardly, inserting the closed end thereof between the outer end of the pin 12 and the vertical member 16 until the eye or slot thereof will receive the pin, and then fiexing the trace or tug inwardly. Thereafter the trace or cockeye will not become accidentally released from the device, since the vertical member and the rear extension 15 prevent outward movement thereof along the pin 12 unless the trace or tug is flexed outwardly a relatively great distance, and such exure would not ordinarily occur through accidental causes.

In the construction shown in Fig. 3 the arm 13, top bar 14, and rear extension 15 are duplicated below the pin 12, as indicated by the numerals 13a, 14a, and 15a, thus duplieating the construction of the guard above and below the. pin.

In the construction shown in Figs. 4, 5, and 6 a stem 19, formed as a screw, is mounted in the end portion of a swingletree 11, anda hook 20 extends longitudinally and rearwardly from the extremity of said stem. A guard is formed and shaped as follows: ,An arm 21 rises from an integral connection with the outer end portion of the stem 19,

contiguous to the hook 20, a rear extension 22 projects from an integral connection with the upper end portion of the arm 21, a top bar 23 extends outwardly from an integral connection with the rear end portion of the rear extension 22 in a plane parallel with and above and to the rear of the body portion of the hook 20, a front extension 24 projects forward from an integral connection with the outer end of the top bar 23 in a plane parallel with the rear extension and above and beyond the rearward-bent portion of the hook 20, a vertical member 25 drops from an integral connection with the forward end of the front extension 24 across the horizontal plane of the hook 20, and a bottom arm 26 extends rearward from an integral connection with the lower end of the vertical member in a plane parallel with the front extension 24 and below the horizontal plane of the hook 20. In attaching a trace end or cockeye to this form of device it is necessary to flex the trace or tug inwardly, insert the trace end or cockeye between the elbow of the hook 20 and the vertical member 24 until the hook is received in the eye thereof, and then flex the trace or tug outwardly, the front extension 24, vertical member 25, and bottom arm 26 all aiding the rearwardlybent portion of the hook 2() in retaining` the trace end or cockeye against accidental removal. This construction is specially adapted for use on swingletrees that may drop downward when strain is relaxed, since in the dropped position the top bar 23 engages the trace end or cockeye and aids in retaining it.

In the construction of the device as shown in Figs. 7 and 8 a hook 20a, arm 21a, a rear extension 22, a top bar 23a,a front extension 24, a vertical member 25a, and a bottoni bar 26 are mounted by integral connection of the hook, arm, and rear extension to a ferrule 27, adapted to be mounted on the end portion of a swingletree 1 1. The operation of attaching and detaching a trace end or cocleye relative to this device is the same as described in connection with Figs. 4, 5, and 6.

In the construction of the device shown in Figs. 9 and 1() a ferrule 27 of common form is mounted on an end portion of a swingletree 11 and is provided with a staple 28, projecting from the rear thereof in a common manner. A combined hook and guard is constructed and mounted. on the ferrule as follows: A loop member 29 of circular form, but less than a circle in extent, is mounted concentrically of the ferrule 27 1 and is pivotally or flexibly connected thereto by confinement within the staple 23. An arm 30 extends radially from the upper portion of the loop 29, and a hook 31 extends inwardly and upwardly from an integral connection with said arm intermediate of its ends. An arm 32 extends radially from the lower portion of the loop 29 approximately parallel with the arm 30 and to a slightly further extent, and an arch 33 integrally connects the forward extremities of said arms, one side of the arch being in advance of the other on account of the difference in the lengths of said arms. This device is specially adapted for use with a toggle-link or eockeye. .ln the operation of attaching a cockeye to this form of device said eoclreye is passed between the arms 30 32 (the trace being both flexed outwardly and twisted to permit it) until the eye maybe raised and twisted over the vertical portion of the hook 31, after which operation the coclreye and trace are righted, the former embracing and engaging the horizontal portion of the hook 31 and the latter extending through (or the stem of the coclreye extending through) the arch 33, said arch preventing accidental twisting of the trace suliicient to unseat the eockeye from the hook.

In the construction of the form of device shown in Fig. 11 an arm 30, hook 31, arm 32, and arch 33, identical with corresponding members shown in Figs. 9 and 10, are mounted by integral connection of the rear ends of said. arms with the forward end por tion of a stem 34, said stem adapted tohe mounted in and transversely of an end portion of a swingletree 11 and. formed with a screw on its rear end portion adapted to receive a nut 35. The operation of attaching and detaching a cockeye or toggle-link relative to this device is the same as described in the preceding matter relating to Figs. 9

` and 10.

In the construction shown in Figs. 12 and 13 a plate 36 is formed with a central aperture, an arm 37 extends from the plate at right angles, a forward extension 3S projects in a horizontal plane from an integral connection with the outer end of the arm 37, a vertical member 39 drops from anintegral connection with the fornf'ard. end portion of the forward extension 3S, and a bottom bar 40 extends rearwardly from an integral connection with the lower end of the vertical member parallel with and below the forward extension. A Thook 41 of common form is passed through the central aperture in the lplate 36 and is screwed into the end portion of a swingletree 11, the plate pivoting on the stem of the hook and presenting the various bars and arms thereon as a guard in like manner as above described in connection with Figs. 4, 5, 6, and 7.

I claim as my invention- 1. A swingletree-hook, comprising an engaging device adapted to be mounted on a swingletree and be embraced by an. eye, an arm formed on and rising from said engaging device, a top bar integral with and extending outward from said arm above the engaging device, an extension integral with and extending laterally fiom said top bar, a vertical lIO() IOS IIC

member integral with and extending vertically from said extension, and a cross-arm integral with and extending from said vertical member parallel With said top bar, the vertical member crossing and laterally spaced from the engaging device.
